Abstract
แผ่นเหล็กเหนียวแรงดึงสูงที่มีความแข็งแรงเชิงดึงที่ 980 MPa หรือที่มีความแข็งแรงเชิงดึงที่สูง กว่า พร้อมกับการยืดตัวและความสามารถในการขึ้นรูปปีกโลหะยื่นอย่างดีเยี่ยม, เหมาะสำหรับการอัดขึ้นรูป (press-forming) รูปทรงตัดขวางที่ซับซ้อน เช่น ชิ้นส่วนของรถยนต์, ถูกผลิตขึ้นโดยการปรับเหล็ก หล้าให้ประกอบด้วยสารัตถะสำคัญ ของโครงสร้างเฟสเดี่ยวเฟอร์ไรต์, เพื่อตกตะกอนคาร์ไบด์ที่มี ไททาเนียม, โมลิบดินัม และวานาเดียมที่น้อยกว่า 10 nm ของขนาดอนุภาคเฉลี่ย ในสภาวะกระจาย และ เพื่อให้องค์ประกอบเฉลี่ยของคาร์ไบด์ที่มีไททาเนียม, โมลิบดินัม และวานาเดียมที่เป็นตาม [ V/ (Ti + Mo + V) มากกว่าหรือเท่ากับ 0.3 (อัตราส่วนอะตอม) รูปที่เลือก รูปที่ 2: High tensile steel plate with a tensile strength of 980 MPa or higher tensile strength with excellent elongation and formability of a metal wing, suitable for extrusion. (press-forming) Complex cross-sectional shapes, such as automobile parts, are produced by adjusting steel. Lava contains important substance Of single-phase ferrite structures, to precipitate carbides containing titanium, molybdenum and vanadium at less than 10 nm of average particle size. In the dispersed state and so that the average composition of carbides with titanium, molybdenum and vanadium followed by (V / (Ti + Mo + V) is greater than or equal to 0.3 (atomic ratio).
