1. Suppose that you have measured the strain aging kinetics of a high-strength low-alloy (HSLA) steel and obtained the following results: Aging Temperature (°C) Aging Time (min) ΔΥ (MPa) 150 240 40 130 1800 40 Determine (using a mathematical rather than graphical approach) the time necessary to obtain a strengthening increment, AY, of 40 MPa at an ageing temperature of 120°C. State any assumptions made in order to arrive at your approximation.
