वर्धनीयता
- वर्धनीयता हा असा विशेष गुणधर्म आहे ज्याच्या आधारे एखाद्या सामग्रीवर हातोडा मारला जाऊ शकतो किंवा फाटल्याशिवाय पातळ पत्र्यामध्ये ती गुंडाळता येऊ शकते.
- हा गुणधर्म सामान्यतः तापमान वाढीसह वाढतो.
- वर्धनीयता म्हणजे संपीडन बलाच्या अधीन राहून मोठ्या प्रमाणात विरुपण किंवा प्लास्टिक प्रतिसाद प्रदर्शित करण्याची धातूची क्षमता.
- वर्धनीयता कमी होत जाणाऱ्या क्रमानुसार शिसे, मृदू पोलाद, घडीव लोखंड, चांदी, तांबे आणि ॲल्युमिनियम या अशा काही सामग्री आहेत.
- ग्रॅफाइट कार्बन अणूंच्या दोन पत्र्यांमध्ये मृदू आहे (व्हॅन डेर वॉल्स बल). परंतु प्लास्टिक विरुपणाअभावी (त्याच्या संरचनेत विस्थापनाची हालचाल नाही) हे धातूसारखे वर्धनीय नाही.
