“How can we use heat treatment to increase the strength of a material?”

Often times, when we receive a material, it is not durable enough for our needs. So how can we use a readily available process to increase the strength of a material? Well, let’s use both of our engineering and scientific mindset to find out. Well, we know that if were to introduce an alloy into the crystal structure, then the material would be strengthened. However, if we were to increase the temperature of a material and then rapidly cool it, the material would form a highly regular crystal and the precipitates would seep into the grain boundaries, therefore greatly strengthening the material. This process is known as precipitate hardening and is used to make a variety of materials stronger ranging from everyday aluminum to the internal wing structure of a Boeing 767
