heat-treat

A blacksmith heat-treats a newly forged metal blade.

Definition

1. Verb:
   • To subject a material to a controlled process of heating and cooling: "heat-treat" refers to the industrial process of altering the physical and sometimes chemical properties of a material, typically metal or glass, by heating it to a specific temperature and then cooling it in a controlled manner. This is done to improve hardness, strength, ductility, or other characteristics.

Usage Examples

• Verb:
  • The factory will heat-treat the steel to make it more durable. (The steel will undergo controlled heating and cooling to increase its durability.)
  • Before using the alloy, the engineers must heat-treat it to achieve the desired hardness. (The alloy requires the heat-treatment process for specific mechanical properties.)

Advanced Usage

• "to heat-treat a metal": to apply the process to a metallic object.

  • The blacksmith heat-treated the sword blade to ensure it could withstand combat. (The sword was hardened through heating and cooling.)

• "heat-treated glass": glass that has been strengthened through thermal tempering.

  • The building uses heat-treated glass for its windows to resist breakage. (The glass has been made tougher by the heat-treating process.)

Variants and Related Words

• Heat treatment (noun): the process of heating and cooling a material to alter its properties.

  • Proper heat treatment is essential for manufacturing high-quality tools. (The process itself is referred to as a noun.)

• Heat-treatable (adjective): capable of being heat-treated.

  • This type of aluminum is heat-treatable, meaning it can be strengthened by heat. (The material can undergo the process.)

Synonyms

• Temper: to heat and cool metal to achieve a specific hardness (often a specific type of heat treatment).
• Annealing: a heat-treating process that softens metal by heating and slow cooling.
• Quenching: a rapid cooling step in heat treatment, often to harden metal.

Phrasal Verbs

• Heat-treat up: to increase the intensity or duration of the heat-treating process (less common, technical jargon).
  • We need to heat-treat up the batch to reach the required temper. (Increase the treatment parameters.)
