2011-09-09 Packing fraction:
In an extreme case where the tetragonality factor of the BCT crystal structure is zero, it can be treated as the BCC crystal structure and will have an atomic packing factor of 68%. If the tetragonality
2011-06-08 17-4 PH Y.S FAILURE:
First you need to make sure that the composition is right. If yes, then it could be due to the following reasons: If the yield strength is too low in the solution annealed condition, it could be due
2011-02-28 Differentiating 304 grade stainless steel from 201 grade:
The magnet method will not help and I do not know any other simple and cheap method to differentiate AISI 304 from the less costly austenitic grades. The simplest method I can think of is using a portable
2011-02-02 strain hardening:
When metals are strained, dislocations are generated and glide on certain specific crystallographic glide planes and in certain directions. Dislocations cannot continue their glide forever because they
2010-12-18 work hardening/slip planes:
Slip is a main work hardening mechanism in most metals including pure gold. Because gold has a Face Centered Cubic(FCC) crystal structure, dislocations glide on the {111} planes along the <110> directions
