maybe I should provide more detail:
All annealed samples were heated to 950C and left inside the furnace for 45 minutes to austenitize. after 45 minutes, the furnace was switched off, and the samples were left inside to cool to room temperature over an ~18 hour period. Sample (a) in the...
hi TVP, the annealed samples were left inside the (switched off) furnace overnight. I daresay the cooling time to room temperature was around the 18 hour mark.
Tempering was performed for 45 min and was consistent across all tempered specimens. The only tempering variable that I modified was temperature. The link I posted above is an album that contains three images (above each image you can click a link to get to the next/previous)-- each image shows...
thanks for your response. I should have clarified...I'm not surprised about getting martensite, since I've had a look at the TTT-curves for the alloy and the critical quenching rates are easily obtainable using water. I'm more concerned with the effects of tempering on the annealed and...
Hi everyone, first time poster here so please be gentle ;)
Working on a project that investigates the effects of heat treatment methods on a low-carbon (0.18% C) alloy steel, E110 (17CrNiMo6).
Heat treatment for this material typically involves case-hardening and carburizing, but I wanted to...
