Topics related to "brittle"

annealing
annealing , process in which glass, metals, and other materials are treated to render them less brittle and more workable. Annealing consists of heating the material and then cooling it very slowly and uniformly; the time and temperatures required in the process are set according to the properties d... Read more
bitumen
bitumen a generic term referring to flammable, brown or black mixtures of tarlike hydrocarbons, derived naturally or by distillation from petroleum. It can be in the form of a viscous oil to a brittle solid, including asphalt, tars, and natural mineral waxes. Substances containing bitumens are call... Read more
cerussite
cerussite , colorless to white or gray mineral, sometimes yellowish or greenish, transparent to opaque, very brittle, crystallizing in the orthorhombic system and occurring also in granular and massive form. It is a carbonate of lead, PbCO 3 , formed by the action of carbonate and bicarbonate soluti... Read more
crevasse
crevasse , large crack in the upper surface of a glacier , formed by tension acting upon the brittle ice. Transverse crevasses occur where the grade of the glacier bed becomes suddenly steeper; longitudinal crevasses, where the glacier spreads over a wider valley or plain. Marginal crevasses are du...

malleability
malleability property of a metal describing the ease with which it can be hammered, forged, pressed, or rolled into thin sheets. Metals vary in this respect; pure gold is the most malleable. Silver, copper, aluminum, lead, tin, zinc, and iron are also very malleable. Some heating usually increases ... Read more
Germaine Richier
Germaine Richier , 1904-59, French sculptor. She studied with Bourdelle (1925-29) and after 1940 developed a tortured awareness expressed in powerful, distorted figures. Richier's works embody a brittle tension between mass and surface that influenced numerous younger sculptors. Don Quichotte de la... Read more
tempering
tempering process involving slow and moderate heating to increase the hardness and toughness of metals that have undergone previous heat treatment. Metals are usually hardened (see hardening ) by being heated to high temperatures and quenched rapidly. This treatment causes brittleness, which is re... Read more
lithosphere
lithosphere , brittle uppermost shell of the earth, broken into a number of tectonic plates. The lithosphere consists of the heavy oceanic and lighter continental crusts, and the uppermost portion of the mantle . The crust and mantle are separated by the Moho or Mohorovicic discontinuity (see eart... Read more
rosin
rosin or colophony, hard, brittle, translucent resin , obtained as a solid residue from crude turpentine . Usually pale yellow or amber, its color may vary from brownish-black to transparent depending on the nature of the source of the crude turpentine. Rosin has no taste but often has a fain... Read more
senility
senility , deterioration of body and mind associated with old age. Indications of old age vary in the time of their appearance. Stooped posture, wrinkled skin, decrease in muscle strength, changes in the lens and muscles of the eye, brittleness of bone and stiffness of the joints, and hardening of t... Read more
