I am looking for a history of metallurgy. I have found two books that look interesting Smil: Still the Iron Age https://www.amazon.com/dp/0128042338/?tag=pfamazon01-20 Smith: A History of Metallography https://www.amazon.com/dp/0262691205/?tag=pfamazon01-20 Does anyone have any other suggestions?

A little background: Inspection room is kept at 20 C +/-2 C. Temperature gauge is accurate to +/-.5 C. Outside ambient temperature where parts are kept can vary from 5 C to 38 C. One part in particular is a rotor made of 4340 steel, ~2350mm long, average diameter of 115mm, and weighs ~ 650lbs...

I have a question about the nature of steel. As I understand it to measure the bending strength of a rod of steel there is the yield strength and the tensile strength. On a plotted line for the elastic modulus there is the elastic part to start. Anywhere on this part of the graph a load can be...

What is it like to work as a materials engineer as a civilian with the Department of Defense?

Hello, I've been thinking about if amorphous metal (aka metallic glass) could created by using regular electroplating or if it has to be created by rapid cooling of the metal after molten. There is a method which a thin layer of metal powder is applied to a flat surface where a laser beam melts...

Hi, We are doing a gear box for a two wheeler (for the first time). Most of our benchmarks are of Suzuki and Honda bikes. All their gears are made of SCM420. Surprising part is these gear teeth are formed by cold forging. No machining at all! Now, I was comparing the chemical composition of...

Hello, I'm having a hard time stamping and annealing grade 2 Ti foils (0.0125mm thickness). The ductility appears to decrease significantly after I vacuum anneal the Ti foil after stamping. I'm running them at a vacuum of 10-6, 700 deg C for 2 hrs and I seem to be making them worse than if I...

Hi Everybody, I have often found myself reading through the discussions on these forums but never ended up taking part. I came here today because I desperately need career path/education advise. Many of the people who regularly post on these forums appear to be very knowledgeable so I can't...

[moderator's note: I've decided to allow this question despite the lack of the formatting template - gneill] ladies and gentlemen, my most cordial greeting to you. i write here cause i need a viscosity vs Temperature data table about liquid metals (more specific pure Post-transition metal...

Homework Statement Givens: - Each of the 2 cylindrical posts are 0.5 inches thick. - The posts and chain links are made of galvanized steel of identical material composition. - The posts and chain links are solid. - Each post is permanently fixed to unbreakable surfaces. The surfaces will move...

Hello everyone, I have a request. Can someone please provide me with a metallurgy research design template? I'm starting my 5th year in a MSE PhD program and for the last 3 years my advisor has instructed me to perform experiments on my alloy without reason. And while I thought this was...

Continually breaking a 0.236 dia. pin wrench, tightening a threaded collet-closer in high speed production application. Both ends of 1/2" D2 tool steel, turned down to create pin wrench, one end is bent at 60 degree angle, to allow an awkward reach sometimes necessary. D2 TS is then hardened &...

Homework Statement Pure iron sulfide (FeS2) is fed into an Herreshoff furnace at 25 °C. An 83% of excess air is also fed into the furnace at 25 °C. The solid product consists only of Fe2O3. The solid product reaches a temperature of 1832 °C, and the exhaust gases (8.7% SO2, 9.8% O2, 81.5% N2)...

Homework Statement A certain pyrite ore contains 85% of FeS2 and 15% of inerts. This ore is introduced into a roasting furnace with 20% excess air, in order to oxidize the FeS2 in the reaction: \textrm{FeS}_2 + \frac{11}{4}\textrm{O}_2 \rightarrow \frac{1}{2}\textrm{Fe}_2 \textrm{O}_3 +...

Dear mates: I'm looking for a reference of the chemical engineerin problems: heat transfer unit operation, separation unit operation, grind unit operations, reactor operations for metallurgy and material science industry. Please recommendme the best one you know With all the best...

1. Metallurgy. How much pure gold should be melted with 15 grams of 14-karat gold to produce 18-karat gold? 2. Road Construction. A new machine that deposits cement for a road requires 12 hours to complete a one-half mile section of road. An older machine requires 16 hours to pave the same...

Hi Everyone, We are an Engineering & Services Company mainly working for Power Generations in industrial field, now we have decided to work in powder metallurgy especially in metal injection molding field, for this purpose we need information about the technology & equipment used in this...

Use the diffusion data in the table below for atoms in iron to answer the questions that follow. Assume metastable equilibrium conditions and trace amounts of C in Fe. The gas constant in SI units is 8.314 J (mol K). Diffusion Diffusion Couple Mechanism Q (J mol) D0 (m2 s) C in FCC...

Homework Statement Calculate the minimum mass of carbon needed to reduce 1.00 kg from sufficient zinc oxide. Homework Equations The Attempt at a Solution I think the equation would be 2 ZnO + C = Zn + CO2 I know the molar mass of C is 12.01, O is 16 and Zn is 65.4 I have been...

can you please suggest me good books for material science and metallurgy

I have to ask this...I work at the seashore trolley museum in kennebunkport Maine as a restoration welder/fabricator. I work with old trolleys and old steel from 1907 to the 1950's and they all tell a story. I don't know how to put this to words but let me give it a try. What happens when you...

i read up recrystallization on wikipedia and it said "Recrystallization is a process by which deformed grains are replaced by a new set of undeformed grains that nucleate and grow until the original grains have been entirely consumed." so is recrystallization where the molecules and atoms...

I want to talk about metallurgy on here. I'm studying the history of ferrous metallurgy, and know some simple forms of steel, but I want to know everything I can learn before I go, if I go, into college. Someone help me out. If not, TY anyways.:smile:

My hobby is Knifemaking. In the knifemaking world there is so much mis-information and out right alchemy regarding heat treating and tempering blades that actual fact often becomes lost. Many bladesmiths subscribe to the 3 theory. That is anneal, normalize, quench and temper 3times each...

hi everbody.. i graduated form metallurgy and metarials engineering.. ı want to do my master degree..l've been having trouble choosing the field.. i m intersted in carbon fibers about textile.. but ı didnt take any class for this material.. so what u think carbon fibers ın textile will be...

suggest me... can anybody of you suggest me a good book for metallurgy?

I read in an old metal working book that when a auto body panel is struck sharply with a hammer that for a microsecond or nanosecond there is a vibration or "shock waves" that allows the grains of metal to slip past one another and re-arrange slight. I am desperately looking for an explanation...
