 
 <prompt> Wetin be something wey no dey look the same for crystal structure? Based on di question wey dey before, write small tori wey get di answer. E fit be 1 - 20 sentences. 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 dey heat up to form solution and then cool sharp sharp, these alloys go become much softer pass normal, during di transformation wey no dey involve diffusion, and then dem go harden as dem dey age. Di solutes wey dey inside these 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. These intermetallic alloys dey look like say dem get one crystal structure, but dem dey behave like say dem get different properties, dey hard and small small brittle.```
