Introductory Metallurgy Crossword Puzzle

QUESTIONS LIST:

• metallurgy : the science and technology of metals and alloys.
• coolant : this liquid can be used to help lubricate a cut, help a metal to resist corrosion and keep metals from overheating as they are being sectioned.
• physical : this type of material property cannot be significantly changed and can be identified by a material reaction to forms of energy like heat.
• thermoplastic : this type of polymer is used to mount specimens for metallurgical investigation and can be re-softened and re-melted.
• macroscopic : this level of internal structure in a metal involves structural elements that can be seen with the naked eye, often after some sample preparation.
• elasticity : the ability of a material to bend or deform without permanent deformation.
• ductility : the ability of a material to deform permanently without failure.
• soft : this type or hardness of material can typically be sectioned using a hacksaw.
• strength : a measure of a materials' internal forces which resist applied external forces.
• hardness : the ability of a material to resist permanent indentation.
• toughness : the ability of a material to resist crack propagation.
• etching : the process of preferentially attacking elements of a prepared metallic specimen with an acid to allow for the viewing of microconstituents and grain boundaries.
• mechanical : this type of material property is related to a materials reaction to an applied force.
• atomic : this level of internal structure involves the organization of a metals atoms into repeating patterns like face centered cubic.
