Hi guys, need your help on the below question:
There is this parameter known as thermal diffusivity.
Thermal Diffusivity = k/ p*C, where k= thermal conductivity, p=density and C= Heat Capacity.
The thermal diffusivity value for Steel is 20.11 um^-2/s (melting point at 1810K) and the value for titanium is 8.85 um^-2/s (melting point at 1933K).
Can I say that in this case, titanium will melt faster than steel because the heat that is mostly absorbed by the titanium will cause the melting, whereas steel melt slower because the heat is conducted away?
Or in another words, any material with a lower thermal diffusivity value will melt faster?
Thanks and Best Rgds
