Such steel is then subjected to a preliminary aging treatment in a temp. range of 350W650°C to cause precipitation hardening and is thereafter subjected to secondary cold working at 40W75% reduction of area and further a final aging treatment in a temp. range of 500W 560°C. The maraging steel having ≥300kg/mm
2 tensile strength at a room temp., ≥0.6% tensile elongation at a room temp. and having malleability is thus obtd.

摘要： PURPOSE:To perform solid phase joining with high joining strength by pressurizing and heating the fayed surfaces of materials to be joined consisting of metals via a metallic insert material consisting essentially of the same metal as that of the essential components of the materials to be joined between both surfaces. CONSTITUTION:In the stage of subjecting materials to be joined consisting of metals, more particularly, Ni-base and Co-base superalloys to solid phase welding, the following insert material is used: The Ni-base or Co-base superalloy powder produced by a quick cooling method for molten metal using a twin roll or single roll method or an atomizing method using an inert gas such as Ar or He is used as the insert material. The fayed surfaces of the materials to be joined consisting of the superalloy are heated under pressure and are joined via the insert material. Then the metals are joined in the solid phase by using the insert material contg. no B, whereby high joining strength is obtained.

摘要： PURPOSE:To enable firm junction of the semiconductor strain detector to strain- generating alloy by making Cu be contained in an Au-Ge-Si alloy solder joining an intermediate metal layer composed of Cr, Cu and Au to the strain-generating metal alloy. CONSTITUTION:The strain accompanying the displacement of the strain-generating metal alloy 1 is transmitted to the strain detector 3 through the intermediary of a bonding agent 6, the intermediate metal layer 5 and an insulation film 4 and the output of an electric signal corresponding to the amount of the strain is obtained there. In this case, the laminate structure of Cr, Cu and Au is applied to the intermediate layer 5, while the Au-Ge-Si alloy solder having Cu therein is used as the bonding agent. By controlling this Au-Ge-Si eutectic solder and Cu, and a bonding layer containing Cu in a quantity sufficient for regular hardening is obtained, the strain detector 3 and the strain-generating alloy 7 can be bonded firmly to each other and further the drift of a zero point under the condition of high temperature and overload can be improved.

Less than 0.1wt of C contains and the rest is Fe but 0.1-1wt of the one of Mo, Nb, Zr and W may be added if necessary. After cold working in more than 50% of working degree, age treatment is made at 350-550 deg.C. By this treatment, Fi-Ni base get desirable composition that Ni and Be or Ti metal compound emerge in austenite ground. By this constitution, deformable element having average thermal expansion coefficient less than 4X10 / deg.C, internal friction less than 1X10 and tensible strength more than 85kg/mm is obtained.
