To get sub-category colletion for specific category, you need to used following code.

$categoryId = 5;
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$current_category = $objectManager->create('Magento\Catalog\Model\Category')->load($categoryId);

// Get Sub-Category For Current Categories

$subcategories = $parent_category->getChildrenCategories();
foreach($subcategories as $subcategorie) 
{
   echo $subcategorie->getName();
}
