Title:
SHAPED BODY FORMED OF POWDER
Document Type and Number:
WIPO Patent Application WO/2022/124359
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a shaped body which is able to achieve a good balance between high thermal conductivity and hardness (quenching/tempering hardness and hardness after softening by means of retention at high temperatures); and the present invention provides a shaped body which is formed of an Fe-based alloy powder that contains, in mass%, more than 0.20 but less than 0.60 of C, less than 0.60 of Si, less than 0.90 of Mn, less than 4.00 of Cr, less than 2.00 of Ni, less than 1.20 of Mo, less than 2.00 of W, less than 0.60 of V and less than 0.10 of Al, with the balance being made up of Fe and unavoidable impurities, and which satisfies the formulae (1) to (3) described below.
(1): T1 = 71.7 – 5.9(Mn) – 6.3(Cr) – 2.8(V) – 5.7(Mo) – 1.1(W) - 23.1(C) – 5.8(Ni) – 1.9(Si) – 0.5(Al) – 0.6PC > 32.0
(2): T2 = 80.1 + 2.4(Mn) + 1.6(Si) + 7.1(Cr) – 12.0PC > 50.0
(3) The average size PC of carbides < 3.0 (μm)
