Title: Hot working method of 'sendust(r)' alloy
Inventor: UETAKA SETSUO
IPC: C21D6/00
Filed: 1987-09-11
Abstract: PURPOSE:To enable rolling of the titled alloy to a thin sheet without generating cracks by enclosing the alloy with a superplastic material which develops superplasticity in a specific temp. range as a sheath material. CONSTITUTION:The 'SENDUST(R)' alloy 1 having a component compsn. contg. B is embedded into the sheath material 2 made of a superplastic two-phase 25Cr-6Ni-3Mo stainless steel and after a release material which is water glass is interposed between the alloy and the material, both are hot rolled. Since the temp. to develop the superplasticity and the hot working temp. of the 'SENDUST(R)' alloy are thereby exactly matched, the crystal grain sizes begin to be fined by a trace amt. of B and the hot workability of the 'SENDUST(R)' alloy itself is improved. The thin sheet of 'SENDUST(R)' is thus produced at a god yield and cost without having the working defects such as cracks.
