    摘要： A bearing pressure-resistant member, including a matrix and a carbide dispersed in the matrix, the carbide having an average particle size of not more than 0.3 µm. A C content in an outer surface of the bearing pressure-resistant member is in a range of 0.6 to 1.5 mass percent. A process for making the bearing pressure-resistant member including subjecting a workpiece containing C to either of gas carburizing and gas carbonitriding to enhance the C content in the outer surface of the workpiece to 0.6 to 1.5 mass percent, holding the workpiece at a first temperature (tl) not more than an Ac 1 transformation point under reduced pressure, heating the workpiece to a second temperature (t2) not less than the Ac 1 transformation point under reduced pressure, followed by holding the workpiece at the second temperature (t2), and subjecting the workpiece to quenching.
