Industry standard right now is a copper alloy (usually an aluminum bronze) inner liner to promote heat transfer to the coolant channels and the walls of the channels and outer liner are usually made of an INCONEL alloy, usually either 625 or 718. But INCONEL is VERY expensive and heavy. The...

I looked for solutions on the internet but all of them had given mass and looked for volume , but that isn't given here. I tried something like subtracting the two weights or trying to find mass from the weight but i can't find the correct awnser

I found the density of carbon and iron: ρ_fe=7.87 g/〖cm〗^3 ρ_c=2.26 g/〖cm〗^3 Using equation 2: atom density of iron and carbon N_fe = 8.48e22 cm^-3 N_c = 1.13e23 cm^-3 Using equation 1: macroscopic scatter and absorption cross sections of iron and carbon Σ_a,fe = .217 cm^-1...

I ask the foundry to cast nickel alloys and I took a piece metal to do a chemical test. The element composition of the nickel alloy is Ni 70% Cr 12% Fe 1.2% Mo 2.5%...so far they all are in the allowable range. But I found the alloy also contains W 0.004% ! Is this the normal condition ? ? I...

Do you have any information's about how to calculate the bias spring or the Force needed ? the current necessary to heat the SMA spring for a 4mm stroke ? Thank you

This is a fun one, sort of! I am working on a singing saw that can be amplified with a regular magnetic pick up, from an electric guitar. I made a blade from laser cut1095 blue tempered spring steel (0.042" thick). It sounded great, but after a few months of service, the blade cracked. What is a...

Which alloy is better resistant to corrosion and less easy to get scratched and the paint fall? For kitchen cupboard handle. Thanks a lot.

Also how bullet proof is it? I know it is a titanium nickel alloy so I’m guessing it may be strong with the titanium in it.

What could prevent the discontinuous yield (upper and lower) points during a tensile test on a low alloy steel A706 grade? Thanks.

I'm trying to learn more about this alloy and there is scant little on Google. William Godfrey Lecomber created a copper alloy for use in frictionless bearings and apparently huge amounts were sold to America and South Africa. WGL called the alloy Cantaba and named his farm in Ruthin (which he...

Hi, I recently started studying materials science and I am looking at a particular alloy of Copper Zirconium. I have identified a B1 phase and they call it a CuZr phase, which I 'm finding rather confusing. Initially I thought that CuZr meant that each unit cell in the lattice was composed of...

The washing machine stopped spinning, so I dismantled it. Here's what I found: I'm thinking it might have become a big battery, as the steel drive shaft was embedded in the alloy drive bracket, which in turn had 6 studs bolting it to the stainless steel drum. It was all enclosed in the sealed...

Hello everybody, I am looking for a disgestion procedure of Pb-alloy, so that we can measure the elements with ICP-OES. Pb should be removed, that it doesn't contaminate the system. So far we used HCl for digestion, but the results weren't very good. Elements of interest are: Sn Sb Bi Cu Cd As...

Hello! I am looking for a eutectic (liquid) alloy that includes Strontium and Lithium at or near room temperature. Does anyone have an idea of where to look for it? Thanks!

I'm trying to understand the effect on a metal alloy of UV light (diode or laser) pulsing at about 1MHz. I am assuming that the stirring of atoms will generate heat, possibly moving the alloy to its eutectic point (depending on the alloy) and in particular to atomic motion. Can anyone...

I am looking for an alloy which has its protons in a randomized spin state? I.e. not affected by gravity. Any suggestions? Thank you.

A friend of mine is working with shape memory alloys and he's got one that is behaving strangely. At "low" temperatures a "fresh" solution heat treated sample will form martensite upon cooling, and austenite upon heating as expected. Heat and cool all you want and you get the transformation...

Okay I was trolling youtube (I know its a horrible habit I have that keeps me from sleeping at night) and I came across this BBC video. Its only 47 seconds but it BRIEFLY describes a material that can Focus and concentrate electromagnetic fields and I can't find anythng else on the web, any...

You hear it over and over again, that solder or braze alloy will flow towards the heat. Another way of saying this is it flows towards hotter metal and away from colder metal. I've done enough soldering to see that it certainly appears to be true. But I've never heard, nor have I found, a...

Is it possible to make an alloy with all possible stable (non-radioactive) metals? I've googled around, and I couldn't find one, and also couldn't find a reason why it hasn't been made. If its not possible, what is the reason behind it?

Hi, What is the difference between alloy compounds and solid solutions I understand so far that solid solutions are homogeneous in composition, which must mean that one, two or more different atoms have same crystal packing structure when combined to form a solid solution.
