In the carbon concentration range from 5.72 to 5.83 wt% carbon, which covers the interval where WC coexists with fcc Ni-Fe without other phases (the ‘carbon window’), the Curie temperature rises from 200 to 527 °C. This result indicates the possibility to use the Curie temperature to determine the carbon balance in the system. With thermodynamic calculations and kinetic simulations we can quantitatively establish the correlation between the carbon and tungsten content of the binder phase and the Curie temperature. This strong compositional effect on the Curie temperature is quantitatively very different from the conventional Co-based cemented carbides, with Curie temperatures of about 950–1050 °C.","claims":[{"public_id":"cl_9c7a34b8f4451f4f8527c043b1df1e36","status":"active","text":"In the carbon concentration range from 5.72 to 5.83 wt% carbon, which covers the interval where WC coexists with fcc Ni-Fe without other phases, the Curie temperature rises from 200 to 527 °C.","confidence":0.95,"contributors":[{"id":32,"public_id":"7c402c1b98","public_label":"뀨 (7c402c1b98)","roles":["extraction"],"url":"https://sah.borca.ai/u/7c402c1b98"},{"id":1,"public_id":"12632b8b5f","public_label":"Anonymous (12632b8b5f)","roles":["review"],"url":"https://sah.borca.ai/u/12632b8b5f"}],"url":"https://sah.borca.ai/claims/cl_9c7a34b8f4451f4f8527c043b1df1e36"},{"public_id":"cl_6461b5d543f3c27d6123bfe71903b1db","status":"active","text":"The result indicates the possibility to use the Curie temperature to determine the carbon balance in the system.","confidence":0.8,"contributors":[{"id":32,"public_id":"7c402c1b98","public_label":"뀨 (7c402c1b98)","roles":["extraction"],"url":"https://sah.borca.ai/u/7c402c1b98"},{"id":1,"public_id":"12632b8b5f","public_label":"Anonymous (12632b8b5f)","roles":["review"],"url":"https://sah.borca.ai/u/12632b8b5f"}],"url":"https://sah.borca.ai/claims/cl_6461b5d543f3c27d6123bfe71903b1db"},{"public_id":"cl_712933b4915c2adb67eafbc57230d9a6","status":"active","text":"The strong compositional effect on the Curie temperature is quantitatively very different from conventional Co-based cemented carbides, which have Curie temperatures of about 950–1050 °C.","confidence":0.9,"contributors":[{"id":32,"public_id":"7c402c1b98","public_label":"뀨 (7c402c1b98)","roles":["extraction"],"url":"https://sah.borca.ai/u/7c402c1b98"},{"id":1,"public_id":"12632b8b5f","public_label":"Anonymous (12632b8b5f)","roles":["review"],"url":"https://sah.borca.ai/u/12632b8b5f"}],"url":"https://sah.borca.ai/claims/cl_712933b4915c2adb67eafbc57230d9a6"},{"public_id":"cl_eade2298778d1875e0de566e1b571cb5","status":"active","text":"Thermodynamic calculations and kinetic simulations quantitatively establish the correlation between the carbon and tungsten content of the binder phase and the Curie temperature.","confidence":0.85,"contributors":[{"id":32,"public_id":"7c402c1b98","public_label":"뀨 (7c402c1b98)","roles":["extraction"],"url":"https://sah.borca.ai/u/7c402c1b98"},{"id":1,"public_id":"12632b8b5f","public_label":"Anonymous (12632b8b5f)","roles":["review"],"url":"https://sah.borca.ai/u/12632b8b5f"}],"url":"https://sah.borca.ai/claims/cl_eade2298778d1875e0de566e1b571cb5"}],"concepts":[{"public_id":"co_0f8086a3a9f6d9851a5dd810f4a921fd","status":"active","name":"kinetic simulations","description":"Simulations of time-dependent processes used to quantitatively relate binder composition to the Curie temperature.","types":["method"],"aliases":[],"contributors":[{"id":32,"public_id":"7c402c1b98","public_label":"뀨 (7c402c1b98)","roles":["extraction"],"url":"https://sah.borca.ai/u/7c402c1b98"},{"id":1,"public_id":"12632b8b5f","public_label":"Anonymous (12632b8b5f)","roles":["review"],"url":"https://sah.borca.ai/u/12632b8b5f"}],"url":"https://sah.borca.ai/concepts/co_0f8086a3a9f6d9851a5dd810f4a921fd"},{"public_id":"co_11a1f8183a81a2189302d44829c5914f","status":"active","name":"WC-NiFe cemented carbides","description":"A composite material with WC as the hard phase and a Ni-Fe alloy as the binder phase.","types":["material"],"aliases":["cemented carbide composite"],"contributors":[{"id":32,"public_id":"7c402c1b98","public_label":"뀨 (7c402c1b98)","roles":["extraction"],"url":"https://sah.borca.ai/u/7c402c1b98"},{"id":1,"public_id":"12632b8b5f","public_label":"Anonymous (12632b8b5f)","roles":["review"],"url":"https://sah.borca.ai/u/12632b8b5f"}],"url":"https://sah.borca.ai/concepts/co_11a1f8183a81a2189302d44829c5914f"},{"public_id":"co_390f7581af3dffa3f14195e34492701d","status":"active","name":"carbon balance","description":"The equilibrium carbon content in the system, which can be determined via the Curie temperature.","types":["parameter"],"aliases":[],"contributors":[{"id":32,"public_id":"7c402c1b98","public_label":"뀨 (7c402c1b98)","roles":["extraction"],"url":"https://sah.borca.ai/u/7c402c1b98"},{"id":1,"public_id":"12632b8b5f","public_label":"Anonymous (12632b8b5f)","roles":["review"],"url":"https://sah.borca.ai/u/12632b8b5f"}],"url":"https://sah.borca.ai/concepts/co_390f7581af3dffa3f14195e34492701d"},{"public_id":"co_3a7e1c1b6819bbc7c3b057658f4908ba","status":"active","name":"Curie temperature","description":"The temperature above which a material loses its permanent magnetization;
