Title: Vacuum rolling joining of different kinds of metals
Inventor: IWAMOTO KIYOBUMI
IPC: B23K20/24
Filed: 1998-09-24
Abstract: PROBLEM TO BE SOLVED: To realize direct joining of different kinds of metals by heating vacuum rolling. SOLUTION: When two sheets of different kinds of metals 4, 5 are heated in a vacuum and are rolled lapped together, a joining surface of the metal 4 of one of the different metals is subjected to surface treatment in association with roughness. It is effective to execute surface treatment also on the joining surface of the other metal 5 in association with roughness. The roughness is preferably <=3.0 S after surface treatment, and is further preferably <=2.2 S. In the direct joining of aluminum alloy and welding carbon steel for structure, the roughness of both the joining surfaces is above all preferably <=2.2 S.  Considering from the nature of rolling joining by which increase in joining area and wedge effect joining or others by rugged fitting are expected, it was considered that it was preferable at the beginning that surface roughness is big to some extent, but direct joining becomes possible by suppressing the roughness within an upper limit.

Title: Method for pickling iron-nickel based low thermal expansion coefficient alloy product
Inventor: SHIRAI MASAO
IPC: C23G1/08
Filed: 1997-10-06
Abstract: PROBLEM TO BE SOLVED: To efficiently execute pickling without the occurrence of pitting, etc. by immersing a material to be treated for a specific time into an aq. soln. of a specific temp. contg. nitric acid and hydrofluoric acid of specific compsns. SOLUTION: A pickling liquid has a nitric acid concn. of 5 to 10 wt.% and a hydrofluoric acid concn. of 1.5 to 3 wt.%. The treatment temp. (temp. of pickling liquid) is managed to 20 to 45 deg.C and the treatment time (immersion time) to 1 to 15 minutes. the nitric acid and the hydrofluoric acid are commonly used for the pickling stainless steels and the processing of Fe-Ni based low expansion coefft. alloys is often carried out in a factory handling the stainless steels and, therefore, the nitric acid and the hydrofluoric acid are advantageous in terms of easy diversion thereto. When the concn. of either of the nitric acid or the hydrofluoric acid exceeds its upper limit value, the pitting is liable to occur in the material to be treated. The degradation in the pickling capability is resulted at the concn. below the lower limit value.  If the treatment temp. exceeds the upper limit value, the pitting arises in the material to be treated and the degradation in the pickling capability is resulted at the temp. below the lower limit value. Then, the immersion time is preferably made shorter when the concn. and temp. of the acid is high.
