Further, the amount of (Al+Ti) and the amount of (W+1/2.Mo) are regulated to values within the range enclosed with lines connecting points A, B, C, D, and E in a figure showing a compositional range. This alloy is held at 1160 to 1225 deg.C for 1 to 4 hr to undergo first-stage solution heat treatment. Subsequently, the alloy is cooled at (50 to 200) deg.C/h cooling rate down to 1000 to 1080 deg.C second-stage solution heat treatment temperature and held for 0. 5 to 4 hr, followed by rapid cooling down to room temperature at a cooling rate of 1000 deg.C/h. Then, stabilizing treatment and aging treatment are applied.

摘要： PROBLEM TO BE SOLVED: To estimate a working temperature of Co group heat resistant alloys with high accuracy by using a correlation curve related to a Larson-Miller parameter(LMP) value. SOLUTION: Heating materials of plural Co group heat resistant allays ECY 768 are heated at about 750 to 1000 deg.C for about 5000 hours at the longest in the atmosphere, and secondary carbide is observed on the respective heating materials by a scanning electron microscope, and a change in the average area is quantitatively determined by an image processor. The average area of this secondary carbide shows an excellent correlation with an LMP value being a function of a temperature and time, and the LMP value corresponding to the average area of the secondary carbide is read from this correlation curve, and a metal temperature can be estimated from it and known operation time. Here, the LMP value can be expressed by (273+T)×(C+log t) by using a heating temperature T deg.C, heating working time (t) and a time constant C. A working temperature of the heat resistant alloys ECY 768 can be accurately estimated by this method.

摘要： PURPOSE:To obtain the sintered metal sound absorber which is superior in sound absorption characteristics and heat resistance and free from a scatter of heat-resisting fiber by using a wall material which uses sintered metal whose grading is within a specific range as the sound absorber. CONSTITUTION:Stainless steel particles which contain >=20% Cr are used and sintered to 3.30g/cm sintering density, 50-500mum grain size, and MKS-rayls/ m flow resistance. When the grading range of alloy powder of stainless steel is set to 250-12 meshes at the time of manufacture, the mean grain size of the sintered metal is 50-500mum. A sound absorbing plate is formed by using this sintered metal; and then the wall material is not too small in grading and the sintered metal sound absorber is obtained which is superior in sound absorption characteristics and high temperature resistance and has pores through which the heat-resisting fiber is not scattered to disappear. This is applicable to an exhaustion silencer for a gas turbine, a silencer for a steam turbine, a silencer for a fan, and other sound prevention walls.
