Description
したがって、必要に応じて要求される特性と生産性を調和することで生産性を落とすことなくコスト面において優れた効果を有するアルミニウム合金が得られる。
そこで、生産性の悪化を極力抑えつつ、必要特性が得られるバランスの取れたアルミニウム合金の開発が課題となっている。
まず、本発明のアルミニウム合金における各添加元素について説明する。
SsとScをSc-Ss≦15μm2に制御することで、押出材の表面性状がよく、押出表層側部と中央部の耐磨耗性特性のばらつきを抑えることができる。共晶Siサイズについて、Ssとは押出材の長手方向に垂直な断面において表層から50μmの深さを基準とし、光学顕微鏡の100倍の視野にて中心側を観察したときの共晶Siサイズである。Ssは同視野にて中心角90度の間隔で4箇所測定したとき、その最大のものとする。Scとは、押出材断面の中心部を光学顕微鏡100倍の視野にて観察した共晶Siサイズである。本発明における共晶Siサイズとは共晶Siの結晶面積をいう。
更に、押出材中の共晶Siサイズが20μm2以下にすることにより表面の粗さを抑えることができる。また、耐摩耗性を得るために、共晶Siの粒数は1000~3000個/mm2とする。共晶Siがサイズ20μm2以下の粒数が1000個/mm2未満では、鍛造後の耐磨耗性の効果が薄い。共晶Siの粒数が3000個/mm2を越えると押出性および鍛造加工性が阻害される。
押出品を鍛造品として使用する場合、鍛造工程での加工性は、材料の硬さが影響を及ぼす。このことから本発明の押出品の調質はF、T1、Oが好ましく、更に好ましい調質はOである。
また、鍛造後における調質は、各々必要に応じた特性により選択すればよいが、本発明ではT6とするのが好ましい。
まず、700℃~740℃の範囲で加熱し、表1に示す組成の合金を溶解しアルミニウム合金溶湯として、金型を用いて鋳造を行った。冷却水量は70~100L/minとなるように制御した。
直径220mmの鋳塊を得た後、この鋳塊を490℃で4時間加熱する均質化処理を施した。この鋳塊を500℃の1穴押出により直径30mmの押出丸棒を作製した。
次に、該押出丸棒を長手方向に100mmの長さで切断し加工率80%の据え込み鍛造を実施した。鍛造品を520℃で2時間の溶体化処理の後、直ちに50℃の温水で焼入れをした。さらに180℃で10時間の人工時効処理を行いT6の調質とした。
ここで、据え込み鍛造の加工率とは、図1において(r1-r2)/r1×100において計算された値である。
(1)据え込み鍛造後の外観
80%据え込み鍛造後の外観を観察し、割れが見られないものを合格(=「○」表記)、割れが見られるものを不合格(=「×」表記)とした。
(2)引張試験
引張試験片は、押出棒の長手方向が試験片の長さ方向になるように採取し、JIS4号試験片を作成し、試験を行った。評価として、引張強さ(TS)が300MPa以上を合格とし、これ未満のものを不合格とする。
(3)摩耗試験
大越式摩耗試験にて比摩耗量を評価した。ここで、試験条件として潤滑油はギヤオイル(75W-90)、相手材をSCM415、摩擦距離を1200m、荷重を19kgfとした。摩擦試験の評価として、比摩耗量を5.0×10-9以下のものを合格、これを超えるものを不合格とした。
本発明例1~10は、組成が好適範囲内であるので表面性状が良い。すなわち、表面がなめらかであるので、押出性がよく生産性が高く製造された。
比較例11~14、16及び17の押出材は、組成が好適範囲外であるため、表面性状に引っかかりのある押出加工性が悪い押出材である。
比較例11の押出材は、Siの含有量が多く、またSc-Ssの値が大きい。そのため表面性状に引っかかりのある押出加工性が悪い押出材である。
比較例12の押出材は、Siの含有量が少なく、またSc-Ssの値が大きい。そのため表面性状に引っかかりのある押出加工性が悪い押出材である。
比較例13の押出材は、Si及びCuの含有量が少ない。そのため表面性状に引っかかりのある押出加工性が悪い押出材である。
比較例14の押出材は、Si、Cu、Mg、及びCrの含有量が多い。そのため表面性状に引っかかりのある押出加工性が悪い押出材である。
比較例16の押出材は、Srが好適範囲外であり、共晶Siサイズが20μm2以下の数が多い。そのため表面性状に引っかかりのある押出加工性が悪い押出材である。
比較例17の押出材は、組成において、Siの含有量が多く、Mgの含有量が少ない、またSc-Ssの値が大きい。そのため表面性状に引っかかりのある押出加工性が悪い押出材である。
比較例15の押出材は、組成は範囲内であるが、Sc-Ssの値が大きいので表面性状に引っかかりのある押出加工性が悪い押出材である。
本発明例1~10の鍛造材は、引張試験、比摩耗量が良い。また、鍛造加工性に優れているため据え込み鍛造後の外観が良い。
比較例11の鍛造材は、組成において、Siの含有量が多いので、据え込み鍛造後の外観に割れが見られる。すなわち、鍛造加工性が悪く、鍛造材としてよくない。
比較例12の鍛造材は、組成において、Siの含有量が少ないので引張強度が劣っており、耐摩耗性が劣っている。また表2より、押出材の共晶Siサイズが20μm2以下の数が少ないので、耐摩耗性が劣っている。
比較例13の鍛造材は、組成において、Si及びCuの含有量は少ないので、引張強度が劣っており、耐摩耗性が劣っている。
比較例14の鍛造材は、組成において、Si、Cu、Mg、及びCrの含有量が多いので、据え込み鍛造後の外観に割れが見られる。すなわち、鍛造加工性が悪く、鍛造材としてよくない。
比較例15の鍛造材は、組成は範囲内であり、据え込み鍛造後の外観、引張試験、比摩耗量がすべて良いが、比較例15の押出材は、表2より、押出加工性が悪く生産性が良くない。従って、比較例15は、鍛造材の生産性が悪い。
比較例16の鍛造材は、組成において、Si、Cu及びSrの含有量が多く、また表2より、押出材の共晶Siサイズが20μm2以下の数が多いので、据え込み鍛造後の外観に割れが見られる。すなわち、鍛造加工性が悪く、鍛造材としてよくない。
比較例17の鍛造材は、組成において、Siの含有量が多く、Mgの含有量が少ないので、据え込み鍛造後の外観に割れが見られる。すなわち、鍛造加工性が悪く、鍛造材としてよくない。
