高週波加熱由於加熱速度快,鍛胚氧化少,並且爐體結構簡單於實施自動化,所以被廣泛應用作為金屬高溫鍛造成形製程的加熱設備。但由於高週波加熱方式具有集膚效應,熱量會稱產生在鍛胚表層,然後再不斷的向胚料中心熱傳延伸,這樣的加熱我有可能會造成鍛胚加熱內外溫度的不均勻,而影響鈦合金鍛件最終的微觀組織與機械性質。本文將高週波加熱裝置應用在鈦合金Ti-6Al-4V外六角輪緣螺栓鍛造,並對高週波感應加熱對鈦合金鍛件機械性質造成的影響作探討。
The induction heater has many advantages for forging heating. They are heating quickly, few oxidization and more simple structure for automation. The induction heater has so many advantages but the skin will study on the hot forging of titanium alloy Ti-6A1-4V bolts heated by induction heater and to find the effect upon the mechanical property.
