Interrupted quenching
WebThe invention relates to a method of interrupted quenching of aluminum alloys with structural hardening. It comprises, from the dissolution: a) rapid cooling, by quenching until the product reaches a temperature between 150 ° and 260 ° C. b) stopping quenching for a few seconds to a few tens of minutes (air cooling) c) resuming quenching to room … WebMar 24, 2024 · Polymer quenching is often used when the material does not respond well to oil quenching. It provides lower cooling rates than fresh or salt water but higher than air. Polymer quenching can accommodate interrupted quenching. This means that the metal can be removed mid-quenching to reduce the chances of distortion without the risk of fire.
