Abstract
Description
【発明の詳細な説明】
造、圧延、機械加工などによって商品化されている。然
し乍ら、Ａ１合金の一部を除き熱処理は施工されていな
い。[Detailed Description of the Invention] It is commercialized by manufacturing, rolling, machining, etc. However, no heat treatment was performed except for a part of the A1 alloy.
本発明は特殊な熱処理によって、これらの材料を強靭化
する方法に関するものである。即ち、これらの材料を超
サブゼロ処理（−１３０℃以下の熱処理）することによ
って強靭化する方法である。The present invention relates to a method of toughening these materials by special heat treatment. That is, this is a method of toughening these materials by subjecting them to ultra-subzero treatment (heat treatment at −130° C. or lower).
超サブゼロ処理は通常寒剤として液体窒素を使用する。Ultra-subzero processing typically uses liquid nitrogen as the cryogen.
液体窒素の沸点は一１９６℃である。従って、この温度
近くまで金属材料を冷却することが可能である。冑、液
体窒素を使用する場合には液体法とガス法の２つの方法
がある。The boiling point of liquid nitrogen is -196°C. Therefore, it is possible to cool the metal material to near this temperature. When using helmets or liquid nitrogen, there are two methods: the liquid method and the gas method.
超サブゼロ処理はこれまで各種工具鋼およびステンレス
鋼について行なわれ、次のような効果をあげている。Ultra-subzero treatment has been applied to various tool steels and stainless steels, and has achieved the following effects.
（１）残留オーステナイトを全部マルテンサイトに変化
させる。(1) All retained austenite is changed to martensite.
（２）耐磨耗性を向上させる。(2) Improve wear resistance.
（３）組織の微細化と微細炭化物の析出が行なわれる。(3) The structure is refined and fine carbides are precipitated.
以上のように超サブゼロ処理は相変化を主体として考案
されたものである。従って、超低温まで相＆ない銅合金
ふ・よび軽合金はこれまで研究の対象とされてふ・らな
かつｋ。As described above, super-subzero processing was devised mainly based on phase change. Therefore, copper alloys and light alloys, which are compatible even at extremely low temperatures, have been the subject of research.
本発明はか−る事情に鑑みなされたものである。The present invention has been made in view of the above circumstances.
即ち、各種の銅合金および軽合金を超サブゼロ処理する
と強靭化することを発見した。強靭化の理論は熱応力に
よる歪の発生、再結晶などが考えられるが未だ解明して
いない。次に各種の銅合金および軽合金を超サブゼロ処
理（液体法）した場合の機械的性質を示す。In other words, it has been discovered that various copper alloys and light alloys can be made tougher by ultra-subzero treatment. The theory of toughening is thought to be the generation of strain due to thermal stress, recrystallization, etc., but this has not yet been elucidated. Next, we will show the mechanical properties of various copper alloys and light alloys subjected to ultra-subzero treatment (liquid method).
実施例
以上のように銅合金および軽合金は超サブゼロ処理を行
なうことによって引張強さが約１０〜２０％、伸び率が
約０〜２０％向上することが判明した。As described in the examples above, it has been found that the tensile strength of copper alloys and light alloys can be improved by about 10 to 20% and the elongation rate can be improved by about 0 to 20% by subjecting them to ultra-subzero treatment.
