“…It can be seen that the microhardness, Hv, is related to the log Z with the following eqs. (3) and (4) for austenitic stainless steel and aluminium respectively: (3) (4) Here, the hardness data for annealed materials were Hv=114.8 and 14.8 kg/mm2 for austenitic stainless steel and aluminium respectively.…”

Subgrain size of austenitic stainless steel type SUS304L and high purity aluminium deformed in torsion at various strain rates and temperatures was measured. And room temperature compression tests were carried out on these samples with subgrain size ranging from about 0.5 to 6,um for austenitic stainless steel and from about 2 to 30 µm for aluminium. The preservation of subgrains formed during high temperature deformation leads to the enhancement of the subsequent mechanical properties of the material. The room temperature strength of substructure strengthened materials correlates well with the size of retained subgrains and is shown to obey the modified Hall-Petch is the strength increment ascribable to the presence of a hot worked substructure. The exponent m was observed to be about unity for these two materials.The strength increment due to the presense of subgrains was observed to be proportional to the powerr of the temperature compensated strain rate in high temperature deformation. The mechanism of substructural strengthening was attributable to the complex arrangement of dislocations in the small angle subgrain boundaries.

This study was conducted to investigate the relationship of rolling reduction with the microstructure and mechanical properties of cold rolled Ti 20V 4Al 1Sn alloy. Cold rolling was performed under the rolling reduction between 10 50. The microstructure was compressed by cold rolling, and became finer. Plastic deformation was partially inhomogeneous in the thickness direction of the cold rolled material. The preferred orientation of the formed crystallographic texture was {112} 〈110〉～ {001} 〈110〉which is typical in metals possessing the bcc structure. The texture evolved with increasing rolling reduction. Hardness and static strength were increased by increase in rolling reduction because of work hardening and microstructural refinement. Anisotropy was induced in yield strength and work hardening exponent by cold rolling; however, it was not marked in hardness and tensile strength.
