The heat-rolled steel plate has: a chemical composition that contains, in mass%, C, Si, Mn, P, S, Al, N and Ti, with the balance being Fe and impurities, and that satisfies Formula (1); and a microstructure containing, in terms of area ratio, 20% or more of bainite, wherein 50% or more in terms of area ratio of the balance is ferrite. In the interior of the heat-rolled steel plate an average value of pole densities of an orientation group {100} to {223} is 4 or less, and a pole density of a {332} crystal orientation is 4.8 or less. In an outer layer of the heat-rolled steel plate, a pole density of a {110} crystal orientation is 2.5 or more. Furthermore, among Ti carbo-nitrides in the heat-rolled steel plate, the number density of fine Ti carbo-nitrides having a particle diameter of 10 nm or less is 1.0×10 17 per cm 3 or less, and a bake hardening amount is 15 MPa or more.

摘要： A process includes: (a) providing a tantalum-coated metal alloy substrate; (b) heat annealing the tantalum-coated metal alloy substrate by heating to an annealing temperature for the tantalum-coated metal alloy substrate, holding at the annealing temperature for a period of time and then quenching to a temperature below 50 degrees Celsius; (c) heating the tantalum-coated metal substrate to the precipitation hardening temperature of the metal alloy substrate; and (d) cooling the tantalum-coated metal alloy substrate to a temperature below 50 degrees Celsius; wherein the process is further characterized by carrying out steps (b)-(d) under a tantalum-inert gas atmosphere and by quenching in step (b) and cooling in step (d) being carried out by flowing a tantalum-inert gas having a temperature of less than 50 degrees Celsius over the tantalum-coated metal alloy substrate.
