(english) Inhomogeneous distribution of alloying elements or phases aligned in filaments or plates parallel to the direction of working.
(english) Element N. 5 of the periodic system. Atomic weight 10.82. It is gray in color, ignites at about 1112 (degrees) F. and burns with a brilliant green flame, but its melting point in a non-oxidizing atmosphere is about 4000 (degrees) F. Boron is used in steel in minute quantities for one purpose only- to increase the hardenability as in case hardening and to increase strength and hardness penetration.
(english) A valve that may be used to divert the flow of fluid in a passage. Most normally configured in a two-way pattern that is either open or closed.
