Answer 1

1, composite materials by two or more different materials, retain their own characteristics, a single material and incomparable, superior performance.
2 and brittle material, tensile strength for the ultimate tensile stress, compression limits on the compressive strength limit for the ultimate stress.
3 and creep refers to the metal material in constant temperature and constant stress under the long-term effects with the extension of time, the material will slowly plastic deformation occurs.
4 and to correct selection, reasonable material, strengthen the new materials technology research and for the development of new materials and expand their application fields are very useful.
5, selection of materials to notice the chemical properties, and process performance, efficiency and availability.
6 and the main purpose of the annealing is to soften the hardness of the steel, machinery processing, namely, to allow for cold.
In July, the welding stress is due to expansion and contraction of uneven.
8 and electrochemical machining is a kind of electrolysis process, rely on electrolysis pool as the cathode and workpiece is used as an anode happen electrochemical decomposition remove metal.
9 and rolling contact bearing no stick-slip effect, starting torque and small friction small operation.
10 and in the grinding suspension, cavitation bubbles collapse produces a lot of pressure

Answer 2

1, composite materials can be two or more combinations of different materials in nature, retain their own characteristics, to be a single material can not match, the superior overall performance.
2, brittle materials, when stretched to the limit tensile strength limit of stress, compressive strength limit of compression in order to limit stress.
3, creep refers to the metal material at a constant temperature and constant stress of the long-term effect, and as the extension of time, materials, plastic deformation will occur slowly phenomenon.
4, to achieve the proper selection, reasonable timber to enhance the application of technology and new materials research, for the development of new materials and expand its application fields are very useful.
5, selection of materials to note that the chemical physical properties, process performance, economy and availability and so on.
6, the main purpose of annealing is to soften the hardness of steel in order to facilitate machining, or cold.
7, welding involved in stress is due to uneven thermal expansion and contraction generated.
8, electrochemical machining is a kind of electrolytic process, relying on electrolytic cell as the cathode and the workpiece as the anode electrochemical decomposition of metal removal.
9, there is no stick-slip effect of rolling contact bearings, starting torque is small, run a small friction.
10, in the abrasive suspension, the collapse of cavitation bubbles will have a lot of pressure.
