Sir, in week 12 assignment question no. 6 there is a question " The surface modification process for a metal system which does not respond to the heat treatment, generally relies on " and the options given are Grain Refinement Mechanical working Precipitation hardening Both a and c but in the lecture 58 which you gave us, you said " The surface modification process for a metal system which does not respond to the heat treatment, generally relies on Work Hardening Methods. " The time was 23:36-23:43 and there is no option of Work hardening in the question. It will be very helpful if you look into this matter. Thank you
