例句與造句

  1. Upon cooling a hypoeutectoid steel from the austenite transformation temperature, small islands of proeutectoid-ferrite will form.
  2. As the solution cools from the upper transformation temperature toward an insoluble state, the excess base metal will often be forced to " crystallize-out, " becoming the proeutectoid.
  3. If the steel is cooled slowly the transformation will agree with the equilibrium predictions and pearlite will dominate the microstructure with some fraction of proeutectoid ferrite or cementite depending on the chemical composition.
  4. Similarly, a hypoeutectoid alloy has two critical temperatures, called " arrests . " Between these two temperatures, the alloy will exist partly as the solution and partly as a separate crystallizing phase, called the " proeutectoid phase . " These two temperatures are called the upper ( A 3 ) and lower ( A 1 ) transformation temperatures.
  5. It's difficult to find proeutectoid in a sentence. 用proeutectoid造句挺難的
