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.
