摘要： PURPOSE:To give intercrystalline corrosion resistance to weld zone by performing long current supply of the specific times the necessary weld time in creating the molten part of a sufficient size at the time of spot welding. CONSTITUTION:In the cace of spot welding of ferrite stainless steel, the long current supply of more than twice the necssary weld time in creating the weld zone of a sufficient size is accomplished. With the weld time of twise or less, the texture change of the weld zone does not take place sufficiently and intercrystalline corrosion resistance is not sufficient and therefore the lower limit is made twice. Hence, the intercrystalline corrosion of the spot weld zone may be prevented without large changes such as sophistication of materials and employment of in-furnace heating.

摘要： PURPOSE:To produce a shape memory alloy having superior workability with high productivity by successively subjecting an alloy consisting of specified percentages of Ni, Mg and Ti to soln. heat treatment, second shape setting and shape memory treatment under specified conditions. CONSTITUTION:An alloy consisting of 50-60wt.% Ni, 0.005-1.00wt.% Mg and the balance essentially Ti is subjected to primary heat treatment (soln. heat treatment) by heating to 650-1,120 deg.C and cooling in vacuum or in an inert gas. A second shape is set to the alloy under + or -0.5-+ or -5% strain and the alloy is subjected to secondary heat treatment (shape memory treatment) by heating to 300-650 deg.C and cooling in the shape restrained state. A shape memory alloy causing small transformation hysteresis between high temp. and low temp. phases and producing a reversible shape memory effect is obtd.

摘要： PURPOSE:To manufacture an NiTi shape memory alloy material having reversible shape change characteristics and small hysteresis by specifying the Ni content in an NiTi alloy as stock, conditions during heat treatment, the extent of strain produced during final shape memory heat treatment, and the cold working rate. CONSTITUTION:A hot worked material of an NiTi shape memory alloy consisting of 50.0-60.0wt% Ni and the balance essentially Ti is cold worked at =650 deg.C for >=1min and 0.2-5.0% strain is produced in the material by final shape memory heat treatment at 300-650 deg.C for >=1min. Thus, a shape memory alloy material having desired characteristics is stably manufactured in such simple treatment shapes.

摘要： PURPOSE: To obtain a hot-rolled plate of an α+β type Ti alloy which is easily workable into a thin plate and has superior cold rollability, by heating the Ti alloy to a temp. in a temp. range whose upper limit is a specified temp. below the β transformation point and by hot rolling the heated alloy in one direction to a prescribed final plate thickness at a prescribed finishing temp.
CONSTITUTION: An α+β type Ti alloy such as a Ti-6Al-4V alloy having 970W 1,000°Cβ transformation point is heated to a temp. in a temp. range whose upper limit is a temp. 20°C below the β transformation point. The heated Ti alloy is hot-rolled in one direction to ≤5mm final plate thickness at ≥700°C finishing temp. A hot-rolled plate of the α+β type Ti alloy which has extremely superior cold rollability and is easily workable into a thin plate can be efficiently manufactured.

摘要： PURPOSE:To give intercrystalline corrosion resistance to the spot weld zone by stopping current supply while holding the pressing after supply of main welding current and supplying postheating current of the specific per cent of the main current after the laps of a short time. CONSTITUTION:In the case of spot welding of ferrite stainless steel, the current supply is stopped while the pressing is held after supply of main welding current, and further the postheating current of 70% or more of the main current is supplied after lapse of a fixed short time. This method is large in postheating current as compared to conventional methods and its weld time is extremely short. This is because the mechanism itself of intercrystalline corrosion resistance impartion differs from the one in conventional methods and this method concerns with the transformation involving the two phase structure of ferrite + martensite containing a slight amount of carbide which is entirely different from the conventional ferrite containing carbide.

摘要： PURPOSE:To facilitate inexpensive and sure joining which can be executed in the atm. by using a brazing filler metal for an NiTi alloy having a specific alloy compsn. CONSTITUTION:The brazing filler metal for the NiTi alloy having the alloy compsn. consisting, by weight %, of 55 to 60% Ag, 20 to 30% Cu and 1 to 10% Sn is used at the time of brazing the NiTi alloy having, for example, a shape memory characteristic. The inexpensive and sure joining which can be executed in the atm. is consequently possible regardless of a spot, line or plane shape. Since the temp. for joining and the joining temp. are higher than the shape heat treating temp. of the shape memory alloy, the shape memory heat treatment after brazing is possible and the formation of more intricately shaped materials is possible as well.
