🔍 Key Concepts

• Heat treatment processes for metals (how they differ) • Difference between hardening, annealing, tempering, and case hardening • What happens to a metal’s hardness and brittleness when it is reheated to a lower temperature after hardening

💭 Think About

• Which process is specifically done after a part has already been hardened to adjust its properties? • Which option describes heating to a lower temperature than the original hardening temperature, then cooling, mainly to reduce brittleness but keep most of the hardness? • Which of these choices is commonly used on tools and machine parts that were too brittle after initial hardening?

✅ Before You Answer

• Verify which process is used to soften and relieve internal stresses (this one is not correct here). • Verify which process is defined as diffusing carbon into the surface of low‑carbon steel (surface only, not whole part). • Identify the process whose main purpose is to reduce brittleness while maintaining hardness, done by reheating below the hardening temperature.
