I am working now on a high-entropy alloy which seems not to recrystallize at high temperature annealing (>0.5Tm).
It is hot forged and has grains of few tens of um with many nanocells inside them. At high T it seems that grains are growing but not recrystallizing and dislocations remain stable...
Hello everyone!
Is it possible to obtain an ultra-fined/nano structure (single grains of 200nm in the structure) just after hot forging?
I have to steels with slightly different compositions. Both of them are rich in Ni and Co, there is also a big amount of Cr and Mn. In one (after the same...
Hello everyone,
I obtained a nanostructured (or maybe rather ultra-fine grained) material (grains of about 200nm) just by hot forging as-cast alloy. This material is based on high entropy alloy (Fe, Cr, Ni, Mn, Co) and it possess FCC structure. Is it possible that some kind of transformation...
Hello everyone,
I have to do a heat treatment (600C and 1000C for 24 hours) of rolled samples (1mm thickness, 40mm length) of austenitic stainless steel and I am not sure if it's ok if I just use argon atmosphere (24h is not very long in my opinion) or it's better if use a glass protection...
