6. FIG. 409 Muscles connecting the upper extremity to the vertebral column. (See enlarged image). The clavicular insertion of this muscle varies in extent; it sometimes reaches as far as the middle of the clavicle, and occasionally may blend with the posterior edge of the Sternocleidomastoideus, or overlap it.
In typical commercial aluminium anodizing processes, the aluminium oxide is grown down into the surface and out from the surface by equal amounts. So anodizing will increase the part dimensions on each surface by half the oxide thickness.
Fig 4 Effect of nitrogen on strain ageing index of steel. Effect during welding â Nitrogen generally affects the toughness of the heat affected zone (HAZ) of welded steel. Since the weld metal should not be weaker in a welded structure, the role of nitrogen is important. The loss of toughness is normally known as HAZ embrittlement.
