Description
思いがけずに本発明による粉末から準備された焼結製品は、高引張り強さ、高靭性、および高寸法精度の組合せによって特徴付けられることがわかった。なお驚くべきことは、これらの性質を、焼結製品に熱処理を行わずに得ることができるということである。したがって、少なくとも800MPaの引張り強さと少なくとも19Jの衝撃強さを併せ持つ焼結製品が、約1120℃、焼結時間約30分で動作する高出力ベルト炉などの費用効果のある焼結装置で得られることがわかった。
a)本質的に、鉄と、任意選択でクロム、マンガン、銅、ニッケル、バナジウム、ニオビウム、ホウ素、ケイ素、モリブデン、およびタングステンからなる群から選択された少なくとも1種の合金元素とからなる水噴霧粉を調製する段階。
b)少なくともH2ガスおよびH2Oガスを含有する雰囲気中で、この粉末を焼なましする段階、
c)脱炭プロセス中に形成された少なくとも1つの炭素酸化物の濃度を測定する段階、または
d)炉の長手方向で互いに所定の距離に位置する少なくとも2点で、本質的に同時に酸素ポテンシャルを測定する段階、または
e)炉内の少なくとも1点で酸素ポテンシャルを測定することと併せて、c)による濃度を測定する段階、
f)この測定の助けを借りて、脱炭雰囲気中のH2Oガスの含有量を調整する段階。
本質的な不活性ガス雰囲気中で気密炉に水噴霧粉を充填し、この炉を閉じる段階、
好ましくは直接電気で加熱しまたはガスで加熱することによって、炉の温度を800〜1350℃の温度に上昇させる段階、
COガスの形成の増加を監視し、COの形成に著しい増加が観察されたときにこの炉からガスを排出する段階、および
COガスの形成の増加が少なくなったときにこの粉末を冷却する段階
を含む。
実施例1
Cr含有量が2重量%から3重量%の間であり、Mo含有量が0.5重量%であり、Mn含有量が0.11重量%である鋼粉末を、特許出願PCT/SE97/01292に記載されているように、水噴霧して焼なましを行った。量が0.3重量%から0.7重量%まで様々な黒鉛(C−UF4)を添加し、同様に潤滑剤H−wax0.8重量%も添加した。粉末を700MPaで成形し、次いでN290%/H210%の雰囲気中で30分間、1120℃で焼結した。以下の表1、2、および3に、準備した製品の圧粉密度(GD)、寸法変化(dl/L)、硬度(Hv10)、引張り強さ(TS)、降伏強さ即ち耐力(YS)、および衝撃エネルギー(シャルピー)を開示する。
