Types of Phase Changes
Melting occurs when a solid changes directly to a liquid. Sublimation occurs when a solid changes directly to a gas. Deposition occurs when a gas changes directly to a solid. Condensation is when a gas changes directly to a liquid.
The 4M is a method that allows to identify and group causes that impact to a specific effect. 4M categories (Material, Method, Machine, Man) are often used in the Cause-Effect Diagram created by Kaoru Ishikawa [9]. It is a good, intermediate tool of problem analysis.
Gold. Gold is the most well-known and investable precious metal. It's unique for its durability (it doesn't corrode), shaping capability, and ability to conduct heat and electricity. While it has some industrial uses in dentistry and electronics, it's primarily used to make jewelry or as a form of currency.
Labourers in metal fabrication remove excess metal and unwanted materials from metal parts, castings and other metal products and perform other labouring activities.
1,000-N grade steel is the world's strongest ultra high strength steel for building structures that was developed to improve the earthquake resistance of buildings and has approximately 2.7 times the yield strength (*2) of conventional 490-N grade steel.
Fabricators are manufacturers of assorted products using various raw materials, tools and their own hands. Their primary responsibilities include reading and understanding assembly instructions, ensuring that the required parts are present and meeting quality control standards.
A hardware prototype is a test unit that meets your specifications. The unit allows your engineers, product managers, and other stakeholders to validate requirements for your application, environment, and budget. It allows for a discovery phase to confirm or reject your initial project hypotheses.
Annealing is a heat treatment process used to reduce hardness, increase ductility and help eliminate internal stresses. Recyrstallisation annealing is applied to cold-worked metal to obtain nucleation and growth of new grains without phase change.
Modern steelmaking processes can be divided into three steps: primary, secondary and tertiary.
The Origins of Metal
All of Earth's metals originated billions of years ago when the universe first appeared. Inside the ultra-hot environment of the stars, simple hydrogen and helium atoms fused to create heavier elements.
