M&P Course Day 4 Quiz Crossword

__________________ - In this, the workpiece is compressed or pushed into the die opening to take the shape of the die hole as its cross section.
______________ - In this process, the workpiece in the form of slab or plate is compressed between two rotating rolls in the thickness direction, so that the thickness is reduced.
_________________ - The workpiece is compressed between two dies containing shaped contours. The die shapes are imparted into the final part.
______________ die forging called as impression die forging is performed in dies which has the impression that will be imparted to the work piece through forming.
In __________ die forging, the work piece is compressed between two flat platens or dies, thus allowing the metal to flow without any restriction in the sideward direction relative to the die surfaces.
_________________ is used to reduce the diameter of a tube or a rod at the end of the work piece to create a tapered section. In general, this process is conducted by means of rotating dies that hammer a workpiece in radial direction inward to taper it as the piece is fed into the dies.
_______________ is the rapid cooling of a work piece in water, oil or air to obtain certain material properties.
_______________ is a process of heat treating, which is used to increase the toughness of iron-based alloys. This process is usually performed after hardening, to reduce some of the excess hardness, and is done by heating the metal to some temperature below the critical point for a certain period of time, then allowing it to cool in still air.
___________________ is a heat treatment that alters the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness, making it more workable. It involves heating a material above its recrystallization temperature, maintaining a suitable temperature for a suitable amount of time, and then cooling.
_____________________ is an annealing process applied to ferrous alloys to give the material a uniform fine-grained structure and to avoid excess softening in steel. It involves heating the steel to 20–50 °C above its upper critical point, soaking it for a short period at that temperature and then allowing it to cool in air.
________________ - hardening or surface hardening is the process of hardening the surface of a metal object while allowing the metal deeper underneath to remain soft, thus forming a thin layer of harder metal at the surface.
The result of metal losings its ductility and becoming brittle due to chemical or physical changes.
________________ is the result of solid material becoming stretched due to tensile stress. A common application of this process is turning metal into wiring.
