Hard alloy die is made y taking high - quality hard alloy as its nips and fastening with steel die case. it is characterized by high hardness, good thermal conductivity, brasive coefficient and strong resistant to corrosion. it is suitable for drawn metal wire, bar and pipes. the types of dies includes rectangle, hecagon, octagon, diamond, trapezoid, basin and knob, u - shaped and half round types
硬質合金模具採用優質合金作模芯，並用鋼質模套緊固，具有硬度高，導熱性能好，磨擦系數小，抗腐蝕性等特點，適用於拉制金屬線材，棒材，管材等，另外，模具的類型有矩型、六角型、八角型、菱型、梯型、凹型凸型、馬蹄型、半圓型等各種異形模。The difference among the elasticity modulus of various microstructures is probably the main reason, which caused the experiment results above. under the same experiment conditions, such as sample shape, size, surface roughness, establishment of testing system, pressure on the probe, and thickness of coupling medium, the variety of relative attenuation coefficient ( or ) in different heat treatment samples is measured and compared by measuring the attenuation obtained from the cylindrical surface of column. the result is as following : for 40cr and 38crmoal, a mt < az mq < a s < a p + f ; for gcrlssimn, a mt < a annea < s < a p + f ; and a increased with the increasing of frequency
在保證試樣形狀、尺寸、表面光潔度、系統參數設置、施加在探頭上的壓力以及耦合層厚度等測試條件一致的情況下，利用棒材圓柱面測衰減系數法，分別測定並比較上述不同熱處理試樣相對衰減系數的變化情況，得到的實驗結果是：對於40cr及38crmoal鋼， _ （低溫回火） （淬火） _ （高溫回火） _ （正火） ；對于gcr15simn鋼， _ （低溫回火） _ （退火） _ （高溫回火） _ （正火） ；且隨著頻率的提高，衰減系數均呈現增加的趨勢。Hot rolled spring steel flat bars - part 1 : flat bars - dimensions and tolerances on shape and dimensions
