(Main)Sintered metal materials, excluding hardmetals - Unnotched impact test piece (ISO 5754:2017)
Sintered metal materials, excluding hardmetals - Unnotched impact test piece (ISO 5754:2017)
ISO 5754 specifies the dimensions of an unnotched impact test piece of sintered metal materials. The test piece may be obtained directly by pressing and sintering or by machining a sintered part.
ISO 5754 applies to all sintered metals and alloys, with the exception of hardmetals. However, for certain materials (for example, materials with low porosity or materials with high ductility), it may be more appropriate to use a notched test piece which, in this case, will give results with less scatter. (In this case, refer to ISO 148‑1.)
NOTE For porous sintered materials, the results obtained from impact tests are not necessarily very accurate compared with results obtained from tests on solid metals.
Sintermetalle, ausgenommen Hartmetalle - Ungekerbte Probe für den Schlagzähigkeitsversuch (ISO 5754:2017)
Dieses Dokument legt die Maße für eine ungekerbte Probe aus Sintermetallen für den Schlagzähigkeits-versuch fest. Der Probekörper darf direkt durch Pressen und Sintern oder durch mechanische Bearbeitung eines gesinterten Teiles hergestellt werden.
Dieses Dokument gilt für alle Sintermetalle und Legierungen, ausgenommen Hartmetalle. Bei bestimmten Werkstoffen (z. B. Werkstoffen mit geringer Porosität oder hoher Duktilität) kann die Verwendung einer gekerbten Probe geeigneter sein, da in diesem Fall Ergebnisse mit geringerer Streuung zu erwarten sind (siehe hierzu ISO 148-1).
ANMERKUNG Bei porösen Sinterwerkstoffen sind die bei den Schlagprüfungen erzielten Ergebnisse nicht unbedingt sehr genau verglichen mit den Ergebnissen, die bei Prüfungen mit festen Metallen erzielt werden.
Matériaux métalliques frittés, à l'exclusion des métaux-durs - Éprouvette non entaillée pour essai de résilience (ISO 5754:2017)
L'ISO 5754 spécifie les dimensions d'une éprouvette non entaillée pour essai de résilience, constituée de matériaux métalliques frittés. L'éprouvette peut être soit obtenue directement par compression et frittage, soit prélevée par usinage sur une pièce frittée.
L'ISO 5754 s'applique à tous les métaux et alliages frittés, à l'exclusion des métaux-durs. Cependant, pour certains matériaux (par exemple, les matériaux à faible porosité, ou à grande ductilité), il peut être plus approprié d'utiliser une éprouvette entaillée qui permet alors de réduire la dispersion des résultats (dans ce cas, voir l'ISO 148‑1).
NOTE Pour les matériaux frittés poreux, les résultats obtenus lors d'essais de résilience peuvent ne pas être très exacts par rapport à ceux obtenus sur des métaux compacts.
Sintrani kovinski materiali, razen trdin - Udarni preskušanec brez zareze (ISO 5754:2017)
Ta dokument določa mere udarnega preskušanca brez zareze iz sintranih kovinskih materialov. Preskušanca se lahko pridobi neposredno s stiskanjem in sintranjem ali s strojno obdelavo sintranega dela. Ta dokument se uporablja za vse sintrane kovine in zlitine razen trdin. Vendar pa je za nekatere materiale (npr. materiale z nizko poroznostjo ali materiale z visoko duktilnostjo) morda bolj primerna uporaba preskušanca z zarezo, ki bo v tem primeru podal rezultate z manj sipanja (v
tem primeru glej standard EN ISO 148-1).
OPOMBA: Za porozne sintrane materiale rezultati, pridobljeni udarnimi preskusi, niso nujno zelo
natančni v primerjavi z rezultati, pridobljenimi pri preskusih s trdnimi kovinami.
