N2 - The strengthening behavior by the repeated strain aging and the low-temperature aging process in maraging steels containing 18% Ni, 8% Co and 5% Mo were investigated by specific heat and electric resistance measurements, as well as by the tensile test. The effect of cold working in the solution treated condition on the tensile strength and on the low temperature aging reaction is not significant. However, in the case of the specimen aged at 475 degree C for a few minutes, cold working greatly increases tensile strength and also promotes the low-temperature aging reaction. The repetition of aging and cold working results in a remarkable increase in tensile strength.
