Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the process categories?Open-die forging and closed-die forging
2. What is the material properties enhancement?Increases tensile strength, fatigue strength, and toughness through grain flow alignment
3. How is forging different from casting?Casting pours liquid metal into a mold, but forging works with solid metal that is hammered or pressed into shape.
4. What are open-die and closed-die forging?Open-die forging uses flat or simple dies and makes large, simple parts, while closed-die forging uses shaped dies that fit the part for precise, complex shapes.

Grain Flow: The directional alignment of the crystalline structure of a metal resulting from plastic deformation.
Plastic Deformation: Permanent change in shape of a material when subjected to stress beyond its elastic limit.
Work Hardening: The strengthening of a metal by plastic deformation, also known as strain hardening.
