I just need the answer choices, you don't need to explain the questions

are forroed by 23 to powders. In metals it is aometimes pouible to process a tentere. to produce smalier crystals, such as in 3433, but in cenamics smallen orywals son 27. (a) boron (b) carbon (c) nitrogen (d) oxygen (c) any of these 28. (a) metallic (b) ionic (c) covalent (d) both a and b (c) both b and c 29. (a) plastic (b) polymerie (c) relaxed (d) elastic (c) coopenative 30. (a) vacancies (b) ions (c) dislocations (d) cracks (c) electrons 31. (a) bonding (b) precipitates (c) grain boundarics (d) bulky side group (c) both a and b 32. (a) sintering (b) annealing (c) combining (d) recryballiaing (o) queaching 33. (a) stainless steel (b) HSLA steels (c) aluminum-lithium alloys (d) eat inon (c) superalloys 34. (a) parer (b) equiaxed (c) finer (d) coarser (c) acicular 35. (a) indoce precipitate formation (b) inhibit dislocation motion (c) hinder crack propagation (d) cause dislocation tangles (c) a corubination of a ad b 36. (a) induce precipitate formation (b) inhibit dislocation motion (c) biader crack propagation (d) canse dislocation tangies (c) a combination of a and b (37-44) Caramies are usually britule because of the presence of 3737. When a stess is mpplied to a ceramic, it tends to 38 at the tips of these defects, which means that the bonds at these points are eloser to 39 . The less deep these defeets, the leas the stress is 838d, becanse there are fewer broken bonds in the defect which are not carrying their share of the load. When you 'cut' glass you don't really eat it, but place a sherp serateh on the surface where it will 39 when you try to bend it. The glas on the outside of the bend gets longer, or in other words has a larger a 41 stress, while that on the inside sees a 42 stress. The thicker the glass, the 43 the increase in length of the outer surface, and the 43 the (c) forees 38. (a) inniluate (b) iniciate (c) propagate (d) concentrate (c) sarunate 39. (a) multiplying (c) slipping 40. (a) modulus (b) strain (c) reactivity (d) stress (c) both a and d 41. (a) compressive (b) shear (c) tensile (d) bend (c) isotropic 42. (a) compressive (b) shear (c) tensile (d) bend (c) isotropic 43. (a) less (b) sroaller (c) greater (d) faster (e) slower
