摘要： There is provided a method of manufacturing an Ni-base superalloy which enables a uniform coat of a glass lubricant to be maintained even after heated to hot forging temperature. The method of manufacturing an Ni-base superalloy in which a forging stock containing an Ni-base superalloy, coated with a lubricant, is subjected to hot forging includes: a preliminary oxidation step of previously generating a Cr oxide coating film having a film thickness of 0.5 to 50 μm on the forging stock thereby to obtain a preliminarily oxidized material; a lubricant coating step of coating the preliminarily oxidized material with a glass lubricant containing borosilicate glass as a main component thereby to obtain a material to be forged; and a hot forging step of hot forging the material to be forged thereby to obtain a hot forged material.

摘要： Copper wire coated with a layer of zinc is heated to a temperature (T.sub.1) sufficient for the formation of a brass phase .beta., and the temperature is maintained until complete diffusion of the zinc. The thickness of the zinc covering can be chosen in such a way that once the zinc is completely diffused, the wire consists of a brass phase .beta. in its periphery and of copper in its central part. The wire is then heated to a temperature (T.sub.2) necessary for the formation of brass phase .alpha., and the central copper part of the wire is transformed into brass phase .alpha..

摘要： There is disclosed a method of reducing a billet of stainless steel containing about 2% of boron without edge cracking of the billet and without loss of the boron from the billet. The billet is coated with zirconia and enclosed in a jacket of mild steel and heated to about 1100*C. and rolled to the desired thickness. The zirconia prevents the billet from adhering to the jacket. The stainless steel is produced by melting rods of a standard stainless steel, for example AISI 304L, with a mild-steel can containing an appropriate quantity of boron powder.
