Copper and copper alloys as specified by the Copper Development Association (CDA) and are designated as C00001 thru C99999 in the Unified Numbering System (UNS). True False An alloy steel designated as AISI 4130 WQT 700 means: chromium-molybdenum alloy steel containing .30% carbon in solution, that is through heat treated and water quenched. True False An AISI 4340 alloy steel contains .43 percent or 43 points of the element carbon in solution. True False Chemicals from which the commercially important plastic resins are derived are themselves derived from natural products that are quite plentiful; these raw materials include coal, water, limestone, sulfur, salt, and petroleum. True False There are two (2) types of polymerization; addition or linear and cross-linked or condensation. Addition polymers are thermoplastics and cross-linked polymers are thermosetting materials. True False

Carbonitriding is a case-hardening process in which a steel is heated in a gaseous atmosphere of such composition that carbon and nitrogen are absorbed simultaneously. Carbonitriding is a modification of the nitriding process. True False Based upon the percent elongation of a tensile sample, a ductile engineering material is defined by a value equal to or greater than 5% and a brittle material is defined by a value less than 5%. True False
Q4: Answer with True or False: 1-Cooling rate when quenching steel in agitated water is faster than brine. 2-Normalizing can be done for hypereutectoid steels by heating the steel above Acm. 3-Marquenching of the hardened steel sometimes causes quench cracks. 4-New carbides type begins to form after tempering AISI 1020 steel after 100°C. 5-Recrystallization temperature decreases with increasing the percentage of prior cold work. 6-Steels are categorized depending on their microstructure and how they've been heat treated. 7-Annihilation of dislocations, polygonization is commercially done by recrystallization annealing 8-Process annealing for cold worked for AISI 1040 steel includes heating the steel to 650°C. 9-Carbon content increases martensite start and finish temperatures. 10-Retained austenite is more at center than surface of a quenched part.
