Context:" <response>: ```On the other hand, most heat-treatable alloys na precipitation hardening alloys, wey dey produce di opposite effects wey steel dey produce. When dem heat am to form solution and then cool am sharp sharp, dis alloys go become much softer pass normal, during di diffusionless transformation, and then go harden as dem dey age. Di solutes for dis alloys go precipitate over time, dey form intermetallic phases, wey dey hard to see from di base metal. Unlike steel, wey di solid solution dey separate to form different crystal phases, precipitation hardening alloys dey separate to form different phases inside di same crystal. Dis intermetallic alloys dey look like say dem get di same crystal structure, but dem dey behave like say dem get different properties, dey hard and small small brittle.```
